A source close to Leites said bout agreements were recently signed and that fight is now official.

Leites was expected to fight in September at UFC Fight Night 15 but will instead return at UFC 90, which takes place Oct. 25 at Allstate Arena just outside Chicago.

Leites will go for his fith straight victory in the UFC since suffering a unanimous-decision loss to Martin Kampmann at his 2006 octagon debut. The 27-year-old Brazilian most recently scored a split-decision victory over Nate Marquardt at UFC 85, though the win was aided by Marquardt's two costly point deductions.

Leites will now meet undefeated Crotian Reljic, who will drop to middleweight for the fight. The fighter, who competed throughout Eastern Europe before signing with the UFC, scored a second-round TKO of Wilson Gouveia at UFC 84. It was his eighth straight victory -- and the seventh to come via stoppage.

I respectfully disagree. Goran trains with Roger Gracie on the regular. I'm sure his sub defense is way above par. If Goran doesn't get the (T)KO, I see him winning by UD. Although, anythings possible.

im picking leeites but wagering heavily on relijic ... he looked alot bigger then goveia in there fight and that was 205 ... so i see him giving leites a extremly hard time but i cant pick against leites but i do have an upset possiblity here

goran is going to win this fight and put thales back out of contention. Goran will be the better striker and the bigger stronger fighter. Thales will get beat on the feet and be desperate for a takedown and wont submit goran and eventually get tko'd by goran.

I'm taking Reljic, picks and for wagers. He will put a beating on Leites. Remember what he did to Gouveia.
